7. Allow the unit to record for at least 3 demand intervals.
8. Stop the recording.
9. View the Apparent Power (KVA), the Active Power (KW) and the Reactive
Power (KVAR).
NOTE: The Power Triangle holds true when the harmonics are off.
S = Apparent Power
P = Active Power
Q = Reactive Power
The power triangle now has increased errors when the harmonics are on. This shows
that power triangle does not hold true for non-sinusoidal waveforms.
Voltage Dips / Sags
1. Verify the Power Quality instrument connected to the simulator has a
programmed sag / dip limit of no more that 10% of the MPQSIM voltage output
that it is connected.
NOTE: If you wish to record RMS values as well it may be best to set the RMS
storage interval to 3 seconds, so you do not need to wait a long period to
acquire saved RMS intervals.
2. Verify the controls are set to their initial settings.
3. Start the unit recording.
4. Allow the unit to record for several seconds.
5. Note there are no recorded Sags / Dip events.
6. Set one of the voltage phase Amplitude selector switches to 85%.
7. Allow the unit to record for several seconds.
8. Set the voltage phase Amplitude selector switch back to 100%.
9. Allow the unit to record for several seconds.
10. Note the unit now displays a Sag / Dip event.
11. Stop the recording.
12. The Sag event can now be viewed on the unit.
